A Tauberian Theorem for Double Cesàro Summability Method

الملخص EN

We have generalized Littlewood Tauberian theorems for ( C , k , r ) summability of double sequences by using oscillating behavior and de la Vallée-Poussin mean.

Further, the generalization of ( C , r ) summability from ( C , k , r ) summability is given as corollaries which were earlier established by the authors.
